For question 22, divide each number by 1.41 to see which one produces a quotient larger than 0.9. d is the answer.
For #23, multiple 0.155 million by 86%, the result is 133,300
again, d is the correct answer.
Answer:
18 and -2
Step-by-step explanation:
Let x = 1st no.
y = 2nd no.
(1) x + y = 16 (2) xy = -36
y = 16 - x x(16 - x) = -36
(x - 18)(x + 2) = 0
x = 18 or x = -2
y = 16 - 18 = -2
y = 16 -(- 2) = 16 + 2 - 18
The two numbers are 18 and -2
Answer:
10/3 hours
Explanation:
If Maria practices 5/6 hours a day, then she practices (5/6)(4) hours in 4 days.
(5/6)(4)=20/6
20/6 can be simplified to 10/3 hours.
I hope this helps!
Answer:
It says not a conic section
Step-by-step explanation:
Answer:
The discriminant is −4, so the equation has no real solutions.
Step-by-step explanation:
In the equation 0 = x² - 4x + 5, a is 1, b is -4, and c is 5.
Plug in these values into b² - 4ac, and simplify:
b² - 4ac
(-4)² - 4(1)(5)
16 - 20
= -4
So, the discriminant is -4. This means that the equation has no real solutions, because the discriminant is a negative number.
The correct answer is that The discriminant is −4, so the equation has no real solutions.
